Real-Time Temperature Mapping in Ultra-Low Freezers as a Standard Quality Assessment [PDF]

Biopreservation and Biobanking, 2019
Adequate preservation of biospecimens has been proven to be critical to obtain reliable and reproducible results in genomics, transcriptomics, proteomics, and many other assays. Most biological assays can be performed on specimens preserved in -80°C ultra-low freezers, but their quality can be influenced by temperature variability within storage units.

Environmental Profiles of Stirling-Cooled and Cascade-Cooled Ultra-Low Temperature Freezers [PDF]

Sustainability, 2012
The environmental footprint of ultra-low temperature (ULT) freezers as used in bio-repositories, universities and other research organizations is investigated. These freezers, employing the cascade refrigeration system, use between 10 and 20 times the energy of an average household refrigerator/freezer.

Reduce energy consumption in your laboratory – switch ultra-low temperature freezers from – 80 °C to –70 °C. A pilot study on short term storage of plasma samples for coagulation testing

Scandinavian Journal of Clinical and Laboratory Investigation
It is common practice in laboratories to store biological samples in ultra-low temperature (ULT) freezers. There is growing interest in raising the temperature of ULT freezers in order to save energy and reduce expenses, as energy conservation becomes increasingly important and sustainable laboratory practices gain popularity. In our laboratory, plasma
